lo tary combustion engine.

Among the objects of the invention is to accumulate a supply of gas mixture, after explosion thereof, and store the same, under pressure, until utilized as amotive power to operate other mechanism. In carrying out this object, the invention provides a sectional stator or casing in which is mounted a rotor operated by the explosion of the mixture, said casing having secured thereto a tank which communicates with the eXplosion chambers through a suitable valve con` trolled port.

Another object is the provision of a novel cooling system for the engine in which there is provided a pump operated by the rotor of the engine to circulate a cooling liquid about the explosion chambers located exteriorly of the rotor and also through the latter and then return to a suitable reservoir.

The inventive idea involved is capable of receiving a variety of mechanical expressions, one of which, for the purpose of illus trating the invention, is shown in the accompanying drawings, in which- Figure 1 is a fragmentary longitudinal section of the engine constructed in accordance with the invention. Fig. 2 is a detail perspective view of one of the packing or division rings used in connection with the invention. Fig. 3 is an enlarged longitudinal section partly broken away. Fig. 4 is a transverse section on the line 4.-4 of Fig. 3.' Fig. 5 is an enlarged fragmentary view of the stator and roto-r of the enginevshowing Fig. 6 is a diagrammatic'illustration of the gearing connecting said movable parts of the invention. y

There is illustrated in the drawings what is now believed to be a preferred form of the invention, in which the engine consists of a sectional casing or stator, substantially circular in cross section and consisting of the sections 10 and 11, the latter preferably having formed integrally therewith a tank 12 the purpose of which will appear in the course of the description. IThe sections are secured together by means of suitable bolts 13 and are provided with a number of communicating cooling chambers 14, the chainbers of the different sections being connected by passages 15.

Mounted'in the bearings 16 at each end of the stator is the hollow cylindrical rotor 17 which at intervals is provided with vanes 17L for forming explosion chambers 19 and partitions 18 for dividing the rotor into sections. In order to effectively separate the different sections the invention provides a division or packing ring 20 for each parti tion which is preferably split and provided on the inner surface of one end thereof with a lug 21 which engages a suitable recess formed in the periphery of the abutment. The outer surfaceV of said` end andthe inner surface of the other end are beveled as indi cated. at 22 so that when the ring is in position there will be no projecting edges and the ring is also preferably provided eX- teriorly thereof with' an annular groove 23 for receiving a tongue 2-1 formed upon the inner surface of the stator.' The inner surface of the ring is provided with an annular tongue 25 for engaging a groove 2G formed in vthe periphery of the abutment of the rotor so thatit will be seen that the ring will effectively prevent any passage of gases from one explosion section to another.

Une end of the rotor 17 has secured thereto a fly wheel 27 and the interior of said rotor communicates through said end with an inlet pipe 28, said pipe having its other end mounted in the stator and commnnicatingfwith the cooling chambers therein. Thefother end of the stator communicates with one end of an outlet pipe 29 they other end of which is mounted in a liquid containing tank 30 adjacent the upper end thereof. Ihe lower end of the tank 30 has one end of a feed pipe 31 mounted therein the other end of which is connected to a circulating pump 32, of any preferred construction. said pump having extending therefrom a pipek 33 which communicates with one 0f the cooling chambers in the stator. It will thus be seen that when the'pump 32 is operated, in a manner to appear in the course of the description, the cooling liquid, preferably water, will be drawn from the tank 30 into the chambers of the stator, thence through the pipe 28 to the interior of the rotor and from thence through the pipe 29 back into the tank 30.

rIhe upper section 10 of the stator is provided with a small sectional casing 34 in which is mounted the rotary cylindical valve 35 having ports 36 arranged at intervals and at different relative positions. One end of the valve 35 is provided with an inlet 37 which is connected through a supply pipe 38 with a pump 39, operated in a manner to presently appear, to inject a combustible mixture into said valve, said pump being connected by a pipe 40 with a carbureter 41, conventionally illustrated in Fig. 4. The top section of the casing 34 has mounted thereon an oil supply pipe 42 having branches 43 extending through said casing whereby the valve is eii'iciently lubricated. The other end of the valve 35 is provided with a spring pressed safety valve 44 which, in case of back-firing, allows escape of the gas to the atmosphere without injury to the valve 35.

The stator is provided with an inlet port 45 for each of the ports 36 in the valve 35, said ports 45 being controlled by the spring pressed valve 46 so that when the port 36 in the valve 35 registers with a port 45 the pressure of the combustible mixture against the valve 46 will open the port 45 and admit said mixture into the explosion chamber 19 where it is ignited by a suitable spark plug 47 mounted in the stator, it being understood that the ignition occurs when the parts are in the position shown in Fig. 4. Just previous to the explosion the abutment 61 in the lower right hand side of Fig. 4 moves to the position shbwn in this figure and Fig. 5

whereupon the explosion of the gas in thechamber will rotate the rotor.

The lower section of the stator, or that portion which is shown interiorly of the tank 12 in Fig. 2, is provided with an outlet port 48 for each chamber, which forms a communication between the different explosion chambers and the interior of said tank, said port being controlled by a spring pressed valve 49 retained in position by a plate 50. This valve permits a certain amount of the exploded gases to escape into the tank 12 from each explosion chamber and it is this fact that provides an unequal pressure in said chambers, thus causing the rotor 17 to rotate. In other words, the pressure of the exploded gas and also a certain amount of pressure from the tank 12, will act against the abutments 61 and propel the rotor in the direction of the arrow in Fig. 2. The, amount of gas passing into the tank is regulated by the pressure of the spring engaging said valve which pressure is always sufficient to elosethe port 48 until the explosion in the chamber occurs. The increased pressure caused by such explosion opens the valve and permits a certain quantity of the gas to pass into the tank but as soon as the pressure is decreased suilieiently the valve again closes leaving sufficient of the gas in the explosion chamber to continue the rotation of the rotor. rIhe stator is provided with an exhaust opening 51 through which the remainder of the gas in the explosion chamber escapes into the exhaust pipe 52 communicating with the atmosphere. It is to be noted that the gas entering the tank 12 is under a certain amount of pressure and as the amount of gas increases the pressure against the valve 49 will likewise increase thus correspondingly decreasing the amount of gas entering the tank. Also, should a charge of the mixture in one of the explosion chambers misfire there will not be sufficient pressure to open the valve 49 and thus the entire charge will escape through the exhaust 52 as soon as the chamber containing the charge registers with the port 51. This will prevent any of the unired mixture from gaining access to the interior of the tank. A suitable outlet (not shown) is provided for the tank 12 in order to permit a supply of the gas therein to be withdrawn and utilized for any purpose desired.

Means are provided for operating the circulating pump 32 and the valve 35 by the rotation of the rotor 17 and such means preferably includes a gear 53 mounted upon the end of the rotor adjacent the supply tank 30 and meshing with a gear 54 which in turn engages a similar gear 55 mounted upon one end of the valve 35. The gear 53 also meshes with a gear 56 mounted upon a shaft 57 of the circulating pump 32. It must be seen that when the gear 53 is rotated a similar motion will be transmitted to the gears 55 and 56 and thereby rotate the valve 35 and the circulating pump 32. Another gear 58 is provided upon a shaft of the pump 39 and meshes with the gear 53 in order to operate said pump to supply the combustible mixture to the valve 35. Another gear 59 may be mounted upon a shaft 60 and mesh with the gear 53 in order to derive power for operating any suitable mechanism such as a magneto.
